Known
by the Maasai people as the "Mountain of God", Ol Doinyo Lengai is
nothing short of spectacular. Rising majestically from the Great Rift Valley
floor to a height of 2890m, Ol Doinyo Lengai is the only active volcano on
planet that erupts carbonatite lava. This type of lava is very unique because
temperatures of these lavas are only around 500°C, about half the temperature
of normal basalt lavas, and its lava flows with a viscosity almost as fluid as
water.

Described
by others as a scientifically precious, geochemical shrine, Oldoinyo lengai's
is quite a physically demanding climb. Its steep slope makes it a challenge to
climb up as well as to climb back down and the day time heat is unbearable. The
best time to climb the mountain is at night when the temperatures are lower.
This allows the climber to witness the amazing sunrise at the summit and come
back down before the scorching heat kicks in.

Given
the long transfer distance, it is best to trek Ol Doinyo Lengai as part of a 3
day tour. Below is a standard 3 day itinerary for Ol Doinyo Lengai but keep in
mind this climb can be an addition to a longer safari tour depending on your
preference.
